To veto a bill means to reject it by exercising a veto power. In the most typical case, a president or monarch vetoes a bill to stop it from becoming law. The veto power is established in many countries constitutions. In the United States, the President has veto power over all bills passed by Congress. Congress can override the Presidents veto by passing the bill again with a two-thirds majority in both the Senate and House of Representatives. If the President does not want the bill to pass, they may simply fail to sign it into law. In other countries, such as Hungary and the United Kingdom, the president or monarch has different options to veto a bill.
